Discuss the dangers of obtaining an injection of amphotericin B with your doctor.
Why is this medication prescribed?
Injections of amphotericin B are used to treat severe and potentially fatal fungal infections. Amphotericin B injection belongs to the group of drugs known as antifungals. It functions by inhibiting the development of infection-causing fungus.
How should this medicine be used?
Amphotericin B injection is sold as a solid powder cake that must be dissolved into a solution before a nurse or doctor may administer it intravenously (into a vein). Amphotericin B injection is typically slowly infused (administered) intravenously once each day over a period of 2 to 6 hours. To determine your tolerance for the medicine, you might receive a test dosage 20 to 30 minutes before to your first dose. Your general health, how well you handle the drug, and the kind of infection you have will all affect how long it takes you to get better.
As you receive an injection of amphotericin B, you could have a response. These responses often occur one to three hours after you begin your infusion and get worse with the first few doses. To lessen these adverse effects, your doctor may recommend additional drugs. If you suffer any of the following symptoms after receiving an amphotericin B injection: fever, chills, loss of appetite, nausea, vomiting, dizziness, breathing issues, or headache, call your doctor right once.
You may receive amphotericin B injection in a hospital or you may use the medication at home. If you will be using amphotericin B injection at home, your healthcare provider will show you how to infuse the medication. Be sure that you understand these directions, and ask your healthcare provider if you have any questions. Ask your healthcare provider what to do if you have any problems infusing amphotericin B injection.
If your symptoms do not improve or get worse while receiving amphotericin B, tell your doctor. If you still have symptoms of infection after you finish amphotericin B injection, tell your doctor.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
